' '1 Claims. (01. 183-84) My invention relates to improvements in fluid the chamber 4, and provided with the usual confilters and is particularly designed tor filtering nection nipples l2. The cooling coil contains a air or gas, and the object of my invention is to ir ulating liquid, such as water, which is o! a provide a device or this type which will remove temperature lower than hat he a or 8 oil, water and condensable gases from air 'or gas being fi t redfiltered t e th u n The entrance to the filter is formed through A further and particular object or my invena nozzle which pe s in h pp po ion tion is to provide a filter which is a combination of the chamber n al y l n olly of a cyclone system and a. stone filter element, thereto, as illustrated'in Fi ure 2. The outlet together with a suitable cooling medium for profrom the filter is P v d by a pipe l4, conlO 7/ ducmg condensation, nected to an orifice II in-the shell I.

The lower it runs into the liquid receiving chamber 5. The end of the shell portion l is continued downdesign or the cyclone separating chamber 4 is wardly to form a cyclone filter chamber 4 or such as to produce an angular velocity in the 5 inverted frusto conical form which opens at its inner spiral B of approximately eight times that lower end into a liquid receiving chamber 5, !urin the outer downward spiral A.

The lower end ejected through the effect of the downward or the shell I is divided from the chamber 4 by a spiral path of the fiuid, is thrown of! by the inhorizontal partition I, having a central orifice ner spiral rotation of the fiuid during its passage 0 8 therein. upwardly towards the orifice 8 into the filter The shell I is designed to contain an inverted stone. filter pot 9, which is inserted by the removal of After the liquid condensate is eliminated from the closure plate 2. The upper face 0! the partithe fluid swirling in the chamber 4, such swirltion I is formed with a. circular recess Ill around ing fiuid passes upwardly through the orifice 0 45 the orifice 8, and of substantially the same diaminto the centre 0! the filter pot 9, wherein it eter as the outer diameter of the filter pot 9, passes over the cooling coil H. As this coil is whereby the bottom of the pot is contained retained at a lower temperature than the fluid within the recess. The filter pot is formed of being filtered, the contact with the coil causes porous stone material held together with a-suitfurther condensation of any cond nso loses 50 able binder, and permits the passage of air or and any contained 011 or water vapour. The gas therethrough, but absorbs any condensate fluid with its condensates, passes through the of oil or water. Interiorly of the filter pot, I fur walls or the filter pot, and as the material strucnish a cooling pipe coil II, which has its inlet ture of the filter pot is such that it absorbs the and outlet ends extending through the wall of condensates and only permits the passage thereas through of air or gas, a thoroughly filtered gaseous fluid will be obtained within the shell I, outside the filter pot and drawn off through the pipe [4.

The filter pot will continue to absorb condensates until it becomes saturated, and when this condition exists, the pot can be readily taken out of the filter by the removal of the closure plate 2 and replaced by another filter, or immediately cleaned with gasoline or some other solvent.

From the foregoing description it will be apparent that I have constructed a very simple and yet eflicient gaseous fluid filter, in which the filtering element can be removed for cleaning or replacement without disturbing the inlet or outlet pipe connections of the filter, and furthermore, through the provision of the cyclone portion of my device, I have provided a means for removing a large proportion of filterable matter before passage to the filler pot, and although I have shown and described a particular embodiment of my invention, it is to be understood that I can make such changes and alterations as I may, from time to time, deem necessary without departing from the spirit of my invention as set forth in the appended claims.

What I claim as my invention is:

1. A fluid filter of the character described. comprising an upper chamber, a lower fluid receiving chamber opening into the upper chamber, a fluid inlet to the filter opening into the lower chamber, a fluid exit opening from the upper chamber, a porous fluid filtering element positioned across the opening between the chembers and through which the fluid passes, and a fluid cooling element so positioned in respect to the porous element, that the fluid in its passage from the lower chamber into the porous element passes over the fluid cooling element.

2. A fluid-filter of the character described, comprising an upper chamber, a lower fluid receiving and fluid swirling chamber opening into the upper chamber, a .fiuid inlet to the filter opening into the lower chamber a fluid exit opening from the upper chamber, a porous fluid filtering element positioned across the opening between the chambers and through which the fluid passes, and a fluid cooling coil positioned below the porous element whereby the fluid in its passage passes over the coil beforeentering the porous element.

3. A fluid filter of the character described, comprising an upper chamber, a lower fluid receiving and fluid swirling chamber of substantially inverted conical form opening into the upper chamber, a fluid inlet opening in a substantially tan gential direction into the fluid swirling chamber a fluid exit openin; from the upper chamber, a porous fluid filtering element positioned across the opening between the chambers and through which the fluid passes, and a fluid cooling element so positioned in respect to the porous element that the fluid in its passage from the lower chamber into the porous element passes over the fluid cool ing element.
